Visualizing the Natural Graphite Supply Problem

Graphite is a critical mineral for lithium-ion batteries, and its battery demand is expected to grow ten-fold by 2030.

Meeting this increasing demand will require a higher supply of both natural graphite and its synthetic counterpart. However, graphite’s entire supply chain is heavily reliant on China, which makes it vulnerable to disruptions while creating environmental challenges.

This infographic from our sponsor Northern Graphite highlights China’s stronghold over the graphite supply chain and outlines the need for new natural graphite mines.

China’s Dominance in the Graphite Supply Chain

From mining natural graphite to manufacturing battery anodes, China dominates every stage of the graphite supply chain.

For example, in 2020, 59% of global natural graphite production came from China. Mozambique, the second-largest producer, churned out 120,000 tonnes—just one-fifth of Chinese production.

Country2020E production, tonnes% of total
China 🇨🇳650,00059.1%
Mozambique 🇲🇿120,00010.9%
Brazil 🇧🇷95,0008.6%
Madagascar 🇲🇬47,0004.3%
India 🇮🇳34,0003.1%

Ukraine 🇺🇦19,0001.7%
Norway 🇳🇴15,0001.4%
Pakistan 🇵🇰13,0001.2%
Canada 🇨🇦10,0000.9%
Rest of the World 🌎73,0006.6%
Total1,100,000100%

China’s massive output makes the other top nine countries look substantially smaller in terms of natural graphite production. Moreover, China also dominates the manufacturing of synthetic graphite and the conversion of graphite into anode material for batteries.

In 2018, China produced nearly 80% of all synthetic graphite, and in 2019, it was responsible for 86% of all battery anode material production. This dependence on graphite supply from China puts the supply chain at risk of political disruptions and makes it unsustainable for the long term.

Unsustainable Production: Natural Graphite vs Synthetic Graphite

The carbon footprint of manufacturing partly depends on the source of energy used in production.

Coal dominates China’s energy mix with a 58% share, followed by petroleum and other liquids. This increases the carbon footprint of all production and especially that of synthetic graphite, which involves energy-intensive heat treatment of petroleum coke.

Energy sourceType% of China's energy consumption (2019)
Coal Fossil fuel58%
Petroleum and other liquidsFossil fuel20%
Hydro Renewable8%
Natural gasFossil fuel8%
Other renewablesRenewable5%
NuclearNon-renewable2%
TotalN/A100%

Percentages may not add to 100% due to rounding.

One study found that producing one kg of synthetic graphite releases 4.9kg of carbon dioxide into the atmosphere, in addition to smaller amounts of sulfur oxide, nitrogen oxide, and particulate matter. While the carbon footprint of natural graphite is substantially smaller, it’s likely that China’s dependence on coal contributes to emissions from production.

Furthermore, concentrated production in China means that all this graphite travels long distances before reaching Western markets like the United States. These extensive shipping distances further exacerbate the risk of disruptions in the graphite supply chain.

The Need for New Sources

As the demand for graphite increases, developing a resilient graphite supply chain is crucial to the European Union and the U.S., both of which have declared graphite a critical mineral.

New graphite mines outside China will be key to meeting graphite’s rising demand and combating a potential supply deficit.

Northern Graphite is positioned to deliver natural graphite in a secure, sustainable, and transparent manner for the green economy.

Visualizing the World’s Largest Copper Producers

Man has relied on copper since prehistoric times. It is a major industrial metal with many applications due to its high ductility, malleability, and electrical conductivity.

Many new technologies critical to fighting climate change, like solar panels and wind turbines, rely on the red metal.

But where does the copper we use come from? Using the U.S. Geological Survey’s data, the above infographic lists the world’s largest copper producing countries in 2021.

The Countries Producing the World’s Copper

Many everyday products depend on minerals, including mobile phones, laptops, homes, and automobiles. Incredibly, every American requires 12 pounds of copper each year to maintain their standard of living.

North, South, and Central America dominate copper production, as these regions collectively host 15 of the 20 largest copper mines.

Chile is the top copper producer in the world, with 27% of global copper production. In addition, the country is home to the two largest mines in the world, Escondida and Collahuasi.

Chile is followed by another South American country, Peru, responsible for 10% of global production.

The Democratic Republic of Congo (DRC) and China share third place, with 8% of global production each. Along with being a top producer, China also consumes 54% of the world’s refined copper.

Copper’s Role in the Green Economy

Technologies critical to the energy transition, such as EVs, batteries, solar panels, and wind turbines require much more copper than conventional fossil fuel based counterparts.

For example, copper usage in EVs is up to four times more than in conventional cars. According to the Copper Alliance, renewable energy systems can require up to 12x more copper compared to traditional energy systems.

Technology2020 Installed Capacity (megawatts)Copper Content (2020, tonnes)2050p Installed Capacity (megawatts)Copper Content (2050p, tonnes)

Visualizing the World’s Largest Hydroelectric Dams

Hydroelectric dams generate 40% of the world’s renewable energy, the largest of any type. View this infographic to learn more.

Visualizing the World’s Largest Hydroelectric Dams

Did you know that hydroelectricity is the world’s biggest source of renewable energy? According to recent figures from the International Renewable Energy Agency (IRENA), it represents 40% of total capacity, ahead of solar (28%) and wind (27%).

This type of energy is generated by hydroelectric power stations, which are essentially large dams that use the water flow to spin a turbine. They can also serve secondary functions such as flow monitoring and flood control.

To help you learn more about hydropower, we’ve visualized the five largest hydroelectric dams in the world, ranked by their maximum output.

Overview of the Data

The following table lists key information about the five dams shown in this graphic, as of 2021. Installed capacity is the maximum amount of power that a plant can generate under full load.

CountryDamRiverInstalled Capacity
(gigawatts)
Dimensions
(meters)
🇨🇳 ChinaThree Gorges DamYangtze River22.5181 x 2,335
🇧🇷 Brazil / 🇵🇾 ParaguayItaipu DamParana River14.0196 x 7,919
🇨🇳 ChinaXiluodu DamJinsha River13.9286 x 700
🇧🇷 BrazilBelo Monte DamXingu River11.290 X 3,545
🇻🇪 VenezuelaGuri DamCaroni River10.2162 x 7,426

At the top of the list is China’s Three Gorges Dam, which opened in 2003. It has an installed capacity of 22.5 gigawatts (GW), which is close to double the second-place Itaipu Dam.

In terms of annual output, the Itaipu Dam actually produces about the same amount of electricity. This is because the Parana River has a low seasonal variance, meaning the flow rate changes very little throughout the year. On the other hand, the Yangtze River has a significant drop in flow for several months of the year.

For a point of comparison, here is the installed capacity of the world’s three largest solar power plants, also as of 2021:

  • Bhadla Solar Park, India: 2.2 GW
  • Hainan Solar Park, China: 2.2 GW
  • Pavagada Solar Park, India: 2.1 GW

Compared to our largest dams, solar plants have a much lower installed capacity. However, in terms of cost (cents per kilowatt-hour), the two are actually quite even.

Closer Look: Three Gorges Dam

The Three Gorges Dam is an engineering marvel, costing over $32 billion to construct. To wrap your head around its massive scale, consider the following facts:

  • The Three Gorges Reservoir (which feeds the dam) contains 39 trillion kg of water (42 billion tons)
  • In terms of area, the reservoir spans 400 square miles (1,045 square km)
  • The mass of this reservoir is large enough to slow the Earth’s rotation by 0.06 microseconds

Of course, any man-made structure this large is bound to have a profound impact on the environment. In a 2010 study, it was found that the dam has triggered over 3,000 earthquakes and landslides since 2003.

The Consequences of Hydroelectric Dams

While hydropower can be cost-effective, there are some legitimate concerns about its long-term sustainability.

For starters, hydroelectric dams require large upstream reservoirs to ensure a consistent supply of water. Flooding new areas of land can disrupt wildlife, degrade water quality, and even cause natural disasters like earthquakes.

Dams can also disrupt the natural flow of rivers. Other studies have found that millions of people living downstream from large dams suffer from food insecurity and flooding.

Whereas the benefits have generally been delivered to urban centers or industrial-scale agricultural developments, river-dependent populations located downstream of dams have experienced a difficult upheaval of their livelihoods.
– Richter, B.D. et al. (2010)

Perhaps the greatest risk to hydropower is climate change itself. For example, due to the rising frequency of droughts, hydroelectric dams in places like California are becoming significantly less economical.
